  • 1.  Introduction Objectives Specifications Payloads End of mission Accomplishment Chandrayaan-2 Conclusion References
  • 2.  CHANDRAYAAN mission was Indias “ first lunar exploration”. It was been launched by a modified version of PSLV C11. It was an unmanned lunar exploration undertaken by ISRO( Indian space research organization) It was launched on 22nd October 2008; 6:23 IST from SATISH DHAWAN SPACE CENTRE , SRIHARIKOTA, ANDHRA PRADESH.
  • 3. Organization Indian Space Research OrganizationMission type OrbiterSatellite of MoonLaunch date 22 October 2008 from Sriharikota, IndiaLaunch vehicle PSLV-C11Mission duration 2 yearsNSSDC ID 2008-052AHome page Chandrayaan-1Mass 523 kg (1,153 lb) Orbital ElementsEccentricity near circularInclination polarApoapsis initial 7,500 km (4,660 mi), final 100 km (62 mi)Periapsis initial 500 km (311 mi), final 100 km (62 mi)
  • 4.  The main objective was to carry out scientific studies and to conduct high- resolution mapping of topographic features in 3D,distribution of various minerals and chemical species such as radioactive nuclides that cover the surface of the moon. To Impact a sub-satellite ( Moon Impact Probe -MIP ) on the surface on the Moon as a fore-runner to future soft landing missions.
  • 5.  Search for surface or sub-surface water- ice on the Moon, specially at lunar poles. Another objective was to harness several science payloads, lunar craft and the launch vehicle with suitable ground support system.
  • 6.  After full integration, the Chandrayaan-1 spacecraft (left) is seen being loaded into the Thermovac Chamber (right)Mass 1380 kg at launch, 675 kg at lunar orbit, and 523 kg after releasing the impactor.Dimensions Cuboid in shape of approximately 1.5 m.Communications X band, 0.7 m diameter parabolic antenna for payload data transmission. The Telemetry, Tracking & Command (TTC) communication operates in S band frequency.
  • 7. Power The spacecraft was mainly powered by its solar array, which included one solar panel covering a total area of 2.15 x 1.8 m generating 700 W of power, which was stored in a 36 A·h Lithium-ion battery.Propulsion The spacecraft used a bipropellant integrated propulsion system to reach lunar orbit as well as orbit and altitude maintenance while orbiting the Moon.Navigation and Control The craft was 3-axis stabilized with two star sensors, gyros and four reaction wheels.

  • 9.  CHANDRAYAAN -1 was sent to moon in a series of orbit increasing man oeuvres around the earth as opposed to the launching of craft on a direct trajectory to moon. Chandrayaan -1 successfully completed the lunar orbit insertion operation on 8th Nov 2008, with this India became the fifth nation to put vehicle in lunar orbit. The MIP landed on lunar surface on 14th Nov 2008, which kept on sending information to the mother satellite. The M3 retrieved the presence of iron and also changes in rock and mineral composition.
  • 10.  ISRO claims that the landing sites of the APOLLO moon mission have been mapped The craft completed 3000 orbits acquiring 70,000 images of lunar surface , which was quite a record. ISRO officials estimated that more than 40,000 images were sent in 75 days. On 26th Nov 2008, TMC acquired images of peaks and craters on the surface. On 25th March 2009, Chandrayaan beamed back the first image of earth.
  • 11.  Chandrayaan-I completed 312 days in orbit It made nearly 3,400 orbits around the moon Indian deep space network (IDSN) noticed a number of technical failures. But ISRO announced that the mission was 90% completed
  • 12.  To construct the complex spacecraft with 11- payloads. To place the spacecraft in a circular orbit around the moon. To place the flag of India on the moon. To carry out imaging operation and to collect data on mineral content. Discovery of large caves on the lunar surface.
  • 13. Moon surface picture taken from theequatorial region by Chandrayaan-1
  • 14. Picture of the lunar surface taken from the polar region by Chandrayaan-1The second picture has been taken over the equatorial region of the Moon. This picture was taken on November 13, 2008, by Chandrayaan-1’s TMC.
  • 15. The American institute of Aeronauticsand Astronautics(AIAA) had selectedISRO’s Chandrayaan-1 mission as one ofits annual AIAA Space 2009 awards.
  • 16. The scientists considered instrumental to the success of the Chandrayaan-1 project are:: G. Madhavan Nair – Chairman, Indian Space Research Organisation T. K. Alex – Director, ISAC (ISRO Satellite Centre) Mylswamy Annadurai – Project director S. K. Shivkumar – Director - Telemetry, Tracking and Command Network. George Koshi –Mission Director Srinivasa Hegde – Mission Director M Y S Prasad – Associate Director of the Sriharikota Complex and Range Operations Director J N Goswami – Director of the Ahmedabad-based Physical Research Laboratory and Principal Scientific Investigator of Chandrayaan-1 Narendra Bhandari – Head, ISRO`s Planetary Sciences and Exploration program.
  • 17.  It is a joint mission proposed by ISRO and Russian Federal Space Agency. The projected cost is Rs 425 crores. The mission is proposed to be launched in 2013 by a GSLV launch vehicle. It includes a lunar orbiter and a rover and a lander. There would be 7 payloads, 5 for the orbiter and 2 for the rover.CURRENT STATUS:: On 30 August 2010, ISRO has finalized payloads for CHANDRAYAAN -2 mission.
  • 18.  India’s first lunar exploration. India has started its journey to moon. The Chandrayaan-1 was one of the “touchstones of India”.
